I am having this problem as well. I took car to SC 5 times already. They replaced the whole chair, the rails, the sensor, a whole new battery to the car (don’t know if it had to do with the short in the seat. It is still unlatching while my kids are in the seat and car is in motion. I thought my kids were playing with the button. So I rode in the seat while my wife drove. And my chair was sliding forward and lifting up like someone was trying to get in 3rd row. SC doesn’t know what to do. I wonder if it falls under a lemon. Hope my experience helps someone.
